The A23 is a dual Cortex-A7. Add the logic to use the IPs used to
control the CPU configuration and the CPU power so that we can
bring up secondary CPUs at boot.

So far the A31s is 100% compatible with the A31, still lets do the same
as what we've done for the A13 / A10s and give it its own compatible string,
in case we need to differentiate later.

The sun6i SMP ops are currently not marked as static, as reported by
sparse. Let's mark it as such.

Now that we can rely on the enable-method, remove the smp field declaration
from A31 machine.

CPU_METHOD_OF_DECLARE allows to bind the smp_ops to a set of cpus through the
enable-method property, instead of relying on the machine to define it. Switch
to it to get closer to an empty machine.

Building an SMP kernel for the sunxi platform with THUMB2 instructions
fails with this error at the moment:
headsmp.S:7: Error: Thumb encoding does not support an immediate here -- `msr cpsr_fsxc,#0xd3'
Since the generic secondary_startup function already does
the same thing in a safe way, we can just drop the private
sunxi implementation and jump straight to secondary_startup.
